1. Respiration

2.  Release of energy from food – DON’T CONFUSE IT WITH GASEOUS EXCHANGE OR BREATHING. Respiration

3.  Release of energy from food.  Occurs in ALL cells; in the c__________ and the m_________ Respiration

4.  Release of energy from food.  Occurs in ALL cells; in the c__________ and the m_________  Respiration

5.  ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER. Sources of energy

6.  ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER.  ATP carries the energy to power EVERY reaction and process in ALL living things. Sources of energy

7.  ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER.  ATP carries the energy to power EVERY reaction and process in ALL living things.  It is then charged up by food molecules – this process is called cellular respiration. Sources of energy

8.  ATP – adenosine triphosphate. UNIVERSAL ENERGY CARRIER.  ATP carries the energy to power EVERY reaction and process in ALL living things.  It is then charged up by food molecules – this process is called cellular respiration.  One molecule of glucose charges up 38 molecules of ATP. Sources of energy

9.  ADP – adenosine diphosphate and ATP are similar. ATP

10.  ADP – adenosine diphosphate and ATP are similar.  ATP carries the energy whereas ADP is the empty carrier. ATP

11.  ADP – adenosine diphosphate and ATP are similar.  ATP carries the energy whereas ADP is the empty carrier.  The last phosphate bond is the high energy bond. ATP

12.  ADP – adenosine diphosphate and ATP are similar.  ATP carries the energy whereas ADP is the empty carrier.  The last phosphate bond is the high energy bond.  This bond is where energy is carried. ATP

13.  ADP – adenosine diphosphate and ATP are similar.  ATP carries the energy whereas ADP is the empty carrier.  The last phosphate bond is the high energy bond.  This bond is where energy is carried.  When ATP (tri) gives up its energy, it loses a phosphate and turns into ADP (di). ATP

14.  ADP – adenosine diphosphate and ATP are similar.  ATP carries the energy whereas ADP is the empty carrier.  The last phosphate bond is the high energy bond.  This bond is where energy is carried.  When ATP (tri) gives up its energy, it loses a phosphate and turns into ADP (di).  ADP then goes back to the cytoplasm and mitochondria to be recharged. ATP

18.  Most of the energy to charge up ADP to ATP comes from the hydrogen in glucose. More carriers - NAD

19.  Most of the energy to charge up ADP to ATP comes from the hydrogen in glucose.  CO2 formed as a waste product is breathed out. More carriers - NAD

20.  Most of the energy to charge up ADP to ATP comes from the hydrogen in glucose.  CO2 formed as a waste product is breathed out.  Hydrogen needs to be carried to the correct place – this is where NAD comes in! More carriers - NAD

21.  Most of the energy to charge up ADP to ATP comes from the hydrogen in glucose.  CO2 formed as a waste product is breathed out.  Hydrogen needs to be carried to the correct place – this is where NAD comes in!  NAD is when it is empty – and NADH2 is when there is hydrogen (see! The H gives it away…) More carriers - NAD
